Just added 50TB to the network, thought I'd share part of my setup
10 X Toshiba 5TB External USB 3

wow, that is a nice setup ! do you run the mining software on Linux? or Windows?
Windows 8.1 with Jminer 30 seconds scan time / Blago 125 seconds
I use Blagos miner when using the GPU for mining Ethereum.
I've used Ubuntu in the past for mining Burst and it worked really well
but not this time due to a bug with the AMD drivers.
